T 0 all whom it may concern:

Be it known that I, HARRY H. SCHROYER, a citizen of the United States, and a resident of the city of Chicago, in the county of Cool: and State of Illinois, have invented certain new and useful Improvements in Car-Diaphragm Hoods; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of referencemarkedthereon, which form a part of this specification.

This application is a continuation of my co-pending application for metallic car diaphragms, filed April 10th, 1916, Serial No. 90,134.

It is an object of this invention to provide a diaphragm hood construction for vestibule diaphragms used on cars and more particularly adapted for use with the metal type of diaphragm, though of course, not limited to exclusive use with this type of diaphragm.

It is also an object ofthis invention to construct a roof or hood structure for use on a telescoping type of metal diaphragm so designed as to permit relative movement imposed upon the elements of the diaphragm by movement of the car to readily take )lace without damaging the diaphragm nor a ecting the weather proof association of the parts. 7

It is also an object of this invention to provide a hood or roof construction for diaphragms having an adjustable weather proof connection with the side walls of the diaphragm and adapted to telescope within stationary means mounted on a car and capable of relative movement with respect to the car and other elements of the diaphragm due to movement between the cars on whlch the diapliragms are mounted.

It is also an object of this invention to construct a roof or hood member for a metal car diaphragm adapted to telescope within stationary means forming a part of the diaphragm and mounted on the car, adjustably connected to the face plate and side walls of the diaphragm to compensate for variation in movement between the coupled cars on which the diaphragms connected to one an other, are mounted.

It is furthermore an object of this invention to construct a top or roof member for a car diaphragm which is adjustably and sealingly associated with the side walls of a diaphragm and adapted to telescope therewith into stationary receiving means mounted on the car, and furthermore adjustably associated with the face plate forming a part of the diaphragm.

It is finally an object of this invention to construct an improved type of hood or roof member for a car diaphragm capable of adjustment to compensate for inequalities in variation of alinement between the parts of the dia ahra m due to movement between coupled cars and acting efliciently to afford a sealing connection at the upper portion of the diaphragm for the passage between the cars.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a fragmentary central vertical section taken through the upper portion of the diaphragm.

Fig. 2 is an enlarged sectional detail showing the telescoping connections of the part shown in Fig. 1.

Fig. 3 is a sectional detail taken on line 38 of Fig. 1.

Fig. 4 is a sectional detail taken on line 4-4 of Fig. 1.

Fig. 5 is a sectional detail taken on line 55 of Fig. 1.

V Fig. 6 is a detail section taken on line 66 of Fig. l.

Fig. 7 is an enlarged detail of the connection of the side walls of the diaphragm to the face plate, showing the head on the margin 21, of slightly different shape.

Fig. 8 is an enlarged sectional detail view of the connection of a side wall plate to the top wall plate of the movable diaphragm section.

As shown in the drawings:

The end of a car body is denoted as a whole by the reference numeral 1, and secured rigidly thereto at the upper end thereof is a horizontal flat metallic receiving compartment comprising a. top wall 2, and a bottom wall 3, with the outer margin of the top wall 2, turned upwardly at right angles, as denoted by the reference numeral 4., and secured in any suitable manner to the body portion of the car; As clearly shown in the enlarged detail view in Fig. 2, thin metallic plates 5 and 6, respectively, are inserted into said compartment flat against the inner surfaces of the respective top and bottom walls 2 and 3, and have secured on each surface thereof a fabric or other sealing material, in the present instance shown preferably as strips of fabric belting, and denoted by the reference numeral 7. EX- tending downwardly of the car body, as clearly shown in Figs. 3 and 5, are narrow compartments comprising an inner wall 8, and an outer wall 9, integrally connected to cured to each of the outer walls 9, and to an upright I-beam frame member 11, forming a part of the car body. Inserted into the open end of the compartment afforded by the walls 8 and 9, are thin metallic strips 12 and 13, having belting or other sealing material 1 1, thereon.

The telescoping sections of the diaphragm adapted to slide within the side wall and top compartments described, consist of side wall plates 15, adju'stably connected as hereinafter described and shown in Figs. 3, 4: and 8, to a top wall plate 16. For this purpose, the upper margins 17, of the respective slde walls 15, are turned inwardly at a right angle, and secured on the under surface of the side margins of the top wall 16, are downwardly ent plates 18, to afford re- {GGSSES' to receive slidably therein the inwardly turned margins 17, of the side walls,

and a strip of sealing material 19, is secured upon the top surface of each of the inwardly turned .portions of the side wall plates sealing against the under surface'of :the top wall plate 16. An adjustable connection is provided for both the side wall plates 15 and the top wall plate 16, at their forward or outer end at the connection thereof to a face plate 20. For this purpose, the

forward margins of each of the side wallplates 15, are bent outwardly as denoted by the reference numeral 22. Secured upon therear face of the face plate 20, is a metallic strip 23, with one margin thereof bent outwardly and spaced away from the surface of the face plate to afford a recess for thereception of the beaded portion 22, of

. saidfside wall plate, so that the same fits snugly and sealingly therein and yet said face plate is capable of angular adjustment withrespect thereto. The top wall plate 16, at its forwardedge, is provided with an upturned margin 24, which abuts against. a

Wear plate 25,, secured upon the rear surface of the vestibuleface plate and engages beneath a plate 26, secured thereto and with the margin thereof spaced therefrom and having a sealing strip 27 mounted-therein to bear closely upon the upturned margin 24:, of said top wall plate.

The operation is as follows:

The side walls 15, and top wall 16, which telescope within the narrow side wall and p comp m nts sec red'rigi-dlynn the ca body, are sealingly and to some extent adjustably held therein and are capable of adj usting movements, so-that the weaving effect which is imposed upon a diaphragmin use is readily taken care ,of without noise or wear .upon the parts. As bufiing and draft stresses take place between coupled cars, the

respective diaphragm sections on the cars are contractedor expanded, as the case may be, the telescoping elements sliding one within the other. Due to the adjustable connection between the top wall and theside walls of the telescoping sections of the diaphragm, it is possible for one side wall to be extended or contracted a greater amount than the other, as for instance when a pair of coupled cars are traveling on a curved track or in switching, the top wall swinging laterally during such movement within the top wall compartment therefor, whichijs considerably wider than the top wall 16, itself, to permit such swinging movement totake place. T he face plate 20, is allowed to assume angled positions with respect to the telescoping sections of the vestibule diaphragm-due-to the yieldable connection between the top and side walls and said face plate, and furthermore said faceplate is capable of sliding vertically to a certain extent to prevent stra n being- Imposed upon the parts due to the weaving effect imposed upon the connected diaphragm sectionsof cars coupled to one another. The stripsofsealing material shown consist of cotton belting, servingto effect a sealing connection between therespective partsof the diaphragm and furthermore to obviate noisy operation thereof.

It is obviousfrom the construction, that the diaphragm is comparatively easy to manufacture and assemble, and is simple in operation, and damage to any one of the parts thereof maybe easily repaired.

I am aware that various details of construction may be varied through a wide range without departing from the principles of thisinvention, and I therefore do-not purpose limiting the patent granted otherwise than necessitated by the prior art.
